I put some gloss varnish on some models the other day to protect them and then brushed on Matte Varnish on the parts that were not meant to be shiny. Some parts see to have gone a little cloudy.
Why is this? Was it to thick? Is there any way to fix it and how do I avoid it in the future?
Thanks
Carl

Maybe the first coat of gloss varnish wasn't completely dry and the remaining solvents are now interacting with the Matte Varnish ?
Another possibility is that the brush-on varnish wasn't homogenous (ie not shaken/stirred) enough.

I agree with gnomehome.
As for avoiding it next time... Allow 24hrs for the first varnish to dry somewhere warm and dry. Also, thin the matte varnish a little so get a thin layer. Make sure the matte varnish is well-mixed too. Finally, allow the matte varnish to dry for 24hrs somewhere warm and dry as well.

Possibly the varnish. But it could also be moisture. A short time under a warm lamp (not too close) should do the trick. 8)

Thanks for the tips guys. Will try it on the next batch of models.

I would suggest varnishing a test model next to see if it turns out ok, following the above recommendations. That way if it still goes wrong, you haven't messed up the batch of models you just referred to.

Yep, allow the base coats to dry fully, paint, inks, washes will all have the effect. Yep mix it well, very well. Another trick is to pre-heat the figures on a radiator before doing it, not hot just warm, it dries them out and gets the temp right for matte. This works really well for spray mattes too.
As for saving it... not managed that yet, had to strip or touch in.

Only small parts were frosted so instead of repainted I tried covering the frost bits with some devlan mud wash. It seemed to be acceptable.

Depends on which brush on matt varnish you are using and temperature.
Daler-Rowney Soluble Matt varnish will go cloudy if it is not shaken well and applied too thickly - the 'talc' settles in crevices.
Any moisture in the air will also give it a 'frosted' effect.
Normally you can recover the figure by applying more gloss varnish.
I always allow my gloss varnish to dry for at least 2 days and normally 1 week before applying the D-R matt in 2 thin coats and as Orctrader states it is thin in application NOT thinned down with thinners.
